For those of you having confirmed injector issues: Did you have a sound that resembled a ball hitting one of these beach boom racquets before the fireworks sounds started?
Two days ago, I heard a faint booming noise when lifting completely off of the throttle above 3000 rpm in 3rd through 6th gear. I can repeat the sound by lifting pretty much at will. Sometimes it was faint, sometimes slightly louder, but very repeatable.
Not suspension or other component related IMHO since I can't replicate it by shifting weight with the brakes, turning, or acceleration, only by lifting off the throttle at ~3000 rpm and up. The sound generator tube has been removed and capped on the intake side, but not the firewall side yet, so the sound could be easily heard through that hole while driving.
Replacing the noise tube setup and bringing the car into the dealer tomorrow.
I'm a very early BRZ, production number 1326 and I have 16XXX miles.
